Rhea-AI Filing Summary

ACNB Corporation reported net income of $15.727 million for the three months ended September 30, 2026, compared with $14.870 million a year earlier; diluted earnings were $1.55 per share versus $1.42. For the first nine months, net income was $44.644 million, compared with $26.246 million. The 2025 nine-month results included $4.2 million, net of taxes, in provision for credit losses on non-PCD loans and $7.9 million, net of taxes, in merger-related expenses associated with the Traditions acquisition.

Third-quarter net interest income was $34.775 million versus $32.137 million, while net interest margin was 4.56% versus 4.27%. Management attributed the net interest income increase primarily to loan growth, loans and investment securities funded at higher rates than those that paid off or matured, and lower funding costs.

At September 30, 2026, total assets were $3,300.976 million, net loans were $2,381.535 million and deposits were $2,508.963 million. ACNB declared a quarterly cash dividend of $0.42 per share.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

The buyback has occurred, while employee-plan shares remain reserved for possible issuance, so repurchases and potential issuance point in opposite directions for the share count.

The buyback has occurred, while employee-plan shares remain reserved for possible issuance, so repurchases and potential issuance point in opposite directions for the share count.

ACNB repurchased 11,288 shares during the third quarter under its April 29, 2026 open-market program, which authorizes purchases of up to 310,000 shares; that ceiling is not a commitment to buy the full amount. Shareholders approved the employee stock purchase plan on May 5, 2026, effective July 1, 2026; it reserves 300,000 shares, and if issued, those additional shares would reduce existing holders’ percentage ownership absent offsetting changes.

non-PCD loans financial
"provision for credit losses on non-PCD loans"
FTE net interest margin financial
"FTE net interest margin increased to 4.56%"
Fully taxable-equivalent (FTE) net interest margin is a bank metric that shows the difference between interest earned on loans and investments and interest paid on deposits and borrowings, adjusted as if tax-exempt income were taxable. It is expressed as a percentage of the bank’s interest-earning assets, making yields on tax-free and taxable instruments comparable. For investors, it helps compare how much core lending and investment activity earns after accounting for tax treatment, like comparing apples priced the same way.
Allowance for Credit Losses financial
"Allowance for Credit Losses"
Allowance for credit losses is a reserve set aside by a financial institution to cover potential losses from borrowers who may not repay their loans. It acts like a safety net, helping the institution prepare for loans that might turn sour. For investors, it signals how cautious the institution is about the quality of its loans and potential risks to its financial health.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Basis of Presentation
Nature of Operations
ACNB Corporation, headquartered in Gettysburg, Pennsylvania, provides banking, wealth management, mortgage and insurance services to businesses and consumers through its wholly-owned subsidiaries, ACNB Bank and ACNB Insurance Services. The Bank engages in full-service commercial and consumer banking and wealth management services, including trust and retail brokerage, through its 33 community banking offices, including 24 community banking office locations in Adams, Cumberland, Franklin, Lancaster and York Counties, Pennsylvania, and nine community banking office locations in Carroll and Frederick Counties, Maryland. There are two loan production offices located in West Lawn, Pennsylvania and in Hunt Valley, Maryland. ACNB Insurance Services is a full-service insurance agency based in Westminster, Maryland, with an additional location in Gettysburg, Pennsylvania. The agency offers a broad range of property, casualty, health, life and disability insurance to both individual and commercial clients.
Recent Acquisition
Effective February 1, 2025, ACNB closed the acquisition of Traditions Bancorp, Inc., holding company for Traditions Bank, York, Pennsylvania. Traditions was merged with and into a wholly-owned subsidiary of ACNB Corporation immediately followed by the merger of Traditions Bank with and into ACNB Bank. ACNB Bank is operating four of the former Traditions Bank offices as “Traditions Bank, A Division of ACNB Bank”.
Basis of Financial Statements
The accompanying unaudited Consolidated Financial Statements have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the amounts of assets and liabilities as of the date of the financial statements as well as revenues and expenses during the period. Actual results could differ from those estimates. In the opinion of management, the accompanying unaudited Consolidated Financial Statements contain all adjustments necessary for a fair presentation. All such adjustments are of a normal recurring nature. These Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the notes included in the Corporation’s Annual Report on Form 10-K for the year ended December 31, 2025. The Corporation evaluates subsequent events through the filing date of this Form 10-Q with the SEC. The results of operations for the three and nine month period ended September 30, 2026, are not necessarily indicative of the results to be expected for the full year.
Certain reclassifications have been made to the prior period financial statements to conform to the current period presentation. Reclassifications had no material effect on prior year net income or stockholders’ equity.
Significant Accounting Policies
The significant accounting policies used in preparation of the Consolidated Financial Statements are disclosed in the Corporation’s 2025 Annual Report on Form 10-K. Those significant accounting policies are unchanged at September 30, 2026.
Accounting Standards Pending Adoption
In November 2024, the FASB issued ASU 2024-03, “Disaggregation of Income Statement Expenses (Subtopic 220-40)”. This ASU is intended to improve the decision usefulness of expense information on public business entities’ income statements through the disaggregation of relevant expense captions in the notes to the financial statements. The amendments of ASU 2024-03 are effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and early adoption is permitted. The Corporation is currently evaluating the impact of this standard, and believes that its adoption will not have a material impact on the Corporation’s Consolidated Financial Statements.
In November 2025, the FASB issued ASU 2025-08, “Financial Instruments–Credit Losses (Topic 326): Purchased Loans”. The amendments in this ASU expand the population of acquired financial assets subject to the gross-up approach in Topic 326. Financial assets acquired with a “more-than-insignificant” deterioration of credit quality since its origination (PCD assets) and non-PCD assets are accounted for using the “gross up approach” to both populations. The amendments in this ASU are effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods, and early adoption is permitted. The amendments in this ASU should be applied prospectively to loans that are acquired on or after the initial application date. The Corporation is currently evaluating the impact of this standard, and believes that its adoption will not have a material impact on the Corporation’s Consolidated Financial Statements.

Table of Contents
In November 2025, the FASB issued ASU 2025-09, “Derivatives and Hedging (Topic 815): Hedge Accounting Improvements”. This ASU was issued to clarify certain aspects of the guidance on hedge accounting and to address several incremental hedge accounting issues arising from the global reference rate reform initiative. The objective of this ASU is to more closely align hedge accounting with the economics of an entity’s risk management activities. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2026, and interim periods within those annual reporting periods, and early adoption is permitted. The Corporation is currently evaluating the impact of this standard, and believes that its adoption will not have a material impact on the Corporation’s Consolidated Financial Statements.
In December 2025, the FASB issued ASU 2025-11, “Interim Reporting (Topic 270): Narrow Scope Improvements”. This ASU was issued to improve the guidance in Topic 270 by improving the navigability of the required interim disclosures and clarifying when that guidance is applicable. The amendments also provide additional guidance on what disclosures should be provided in interim reporting periods. The amendments add to Topic 270 a principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The objective of this amendment is to provide clarity on the current interim reporting requirements. The amendments in this ASU are effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, and early adoption is permitted. The Corporation is currently evaluating the impact of this standard, and believes that its adoption will not have a material impact on the Corporation’s Consolidated Financial Statements.

On May 5, 2026, shareholders approved the ACNB Corporation Employee Stock Purchase Plan effective July 1, 2026.

A total of 300,000 shares of the Corporation’s common stock are reserved for issuance under the ESPP.

All mortgage-backed securities, and those of a similar asset class, are government-sponsored enterprise pass-through instruments issued by the Federal National Mortgage Association or Federal Home Loan Mortgage Corporation or they are issued by the Government National Mortgage Association which is backed by the U.S. government which guarantees the timely payment of principal on these investments.
The Company evaluates AFS debt securities for impairment at each measurement date to determine whether the decline in the fair value below the amortized cost basis is due to credit-related factors or noncredit-related factors. In estimating credit events, management considers whether it intends to sell the security or if it is more likely than not that it will be required to sell the security before anticipated recovery or if it does not expect to recover the entire amortized cost basis. There was no impairment on AFS debt securities as of September 30, 2026 and December 31, 2025. The Company evaluates HTM debt securities for expected credit losses at each measurement date to determine the ACL. The Corporation’s ACL on its HTM investment securities was de minimis as of September 30, 2026 and December 31, 2025.

Collateral-Dependent Loans
A loan is considered to be collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral. For all classes of loans deemed collateral-dependent, the Corporation elected the practical expedient to estimate expected credit losses based on the collateral’s fair value less cost to sell. If the estimated value of the loan is less than the amortized cost basis, the loan is written down through the ACL as a credit loss. Substantially all of the collateral supporting collateral-dependent loans consists of various types of real estate, including residential properties, commercial properties such as retail centers, office buildings and lodging, agriculture land and vacant land. Changes in the fair value of the collateral for individually evaluated loans are reported as a component of the provision for credit losses in the period of change.
The following table presents the amortized cost basis of individually evaluated loans by type of collateral as of the periods presented:

Loan Modifications
The Corporation evaluates all loan restructurings to determine if the restructuring results in a new loan or a continuation of the existing loan. Loan modifications to borrowers experiencing financial difficulty that result in a direct change in the timing or amount of contractual cash flows include situations where there is principal forgiveness, interest rate reductions, other-than-insignificant payment delays, term extensions or combinations of the above. Therefore, the disclosures related to loan restructurings are only for modifications that directly affect cash flows.

As of September 30, 2026, the Corporation had no commitments to lend any additional funds on modified loans. During the nine months ended September 30, 2026, two residential mortgage loans totaling $332 thousand defaulted on the modified terms of the agreement by failure to make the monthly payments as agreed upon in their modification agreements. During the three and nine months ended September 30, 2025, there were no loans modified due to financial difficulty that defaulted subsequent to the modification. For purposes of this disclosure, a default occurs when, within 12 months of the original modification, either a full or partial charge-off occurs or the loan becomes 90 days or more past due.
Allowance for Credit Losses
The Corporation maintains an ACL at a level determined to be adequate by management to absorb expected credit losses associated with the Corporation’s financial instruments over the life of those instruments as of the balance sheet date. The ACL consists of loans evaluated collectively and individually for expected credit losses. The Corporation considers the performance of the loan portfolio and its impact on the ACL and does not assign internal risk ratings to smaller balance, homogeneous loans such as certain residential mortgage, home equity lines of credit, construction loans to individuals secured by residential real estate and consumer loans. For these loans, the Corporation evaluates credit quality based on the aging status of the loan and designates as performing and nonperforming.

Borrowings with original maturities of one year or less are classified as short-term. Securities sold under repurchase agreements are comprised of customer repurchase agreements, which are sweep accounts with next-day maturities utilized by larger commercial customers to earn interest on their funds. Securities are pledged to these customers in an amount at least equal to the outstanding balance. Under an agreement with the FHLB, the Bank has short-term borrowing capacity included within its maximum borrowing capacity. All FHLB advances are collateralized by a security agreement covering qualifying loans. In addition, all FHLB advances are secured by the FHLB capital stock owned by the Bank having a par value of $13.9 million at September 30, 2026.

The long-term FHLB advances have a weighted average rate of 4.42% and are collateralized by the assets defined in the security agreement and FHLB capital stock described previously. Based on this collateral and ACNB’s holding of FHLB stock, ACNB is eligible to borrow up to $1.32 billion, of which $1.03 billion was available at September 30, 2026.
The trust preferred subordinated debt is comprised of debt securities issued by FCBI in December 2006 and assumed by ACNB Corporation through the acquisition of FCBI. FCBI completed the private placement of an aggregate of $6.0 million of trust preferred securities. The interest rate on the subordinated debentures is adjusted quarterly to 163 bps over the three-month CME Term SOFR plus applicable tenor spread adjustment. On September 11, 2026, the most recent interest rate reset date, the

Table of Contents
interest rate was adjusted to 5.79% through the period ending December 14, 2026. The trust preferred securities mature on December 15, 2036, and may be redeemed at par, at the Corporation’s option, on any interest payment date. The trust preferred subordinated debt is considered Tier 1 capital for the consolidated capital ratios.
On March 12, 2026, the Company entered into subordinated note purchase agreements with the Purchasers pursuant to which the Company sold and issued $15.0 million in aggregate principal amount of its 5.875% fixed-to-floating rate subordinated notes due March 15, 2036. The 2026 Subordinated Notes bear interest at a fixed rate, for the period up to, but excluding March 15, 2031. From and including March 15, 2031 until maturity or redemption, the interest rate will adjust to a floating rate equal to a benchmark rate, which is expected to be the then-current Three-Month Term SOFR, plus 245 bps. The Company will pay interest in arrears semi-annually during the fixed interest rate period and quarterly during the floating interest rate period. The 2026 Subordinated Notes constitute unsecured and subordinated obligations of the Company and rank junior in right of payment to any senior indebtedness and obligations to general and secured creditors. Subject to limited exceptions, the Company cannot redeem the 2026 Subordinated Notes before March 15, 2031. The 2026 Subordinated Notes were issued by the Corporation to the Purchasers at a price equal to 100% of their face amount. The issuance costs for the 2026 Subordinated Notes were $538 thousand and are reported net on the Consolidated Statements of Condition. The 2026 Subordinated Notes have a stated maturity of March 15, 2036, are redeemable by the Company at its option, in whole or in part, on or after March 15, 2031, and at any time upon the occurrences of certain events. The 2026 Subordinated Notes are considered Tier 2 capital for the consolidated capital ratios.
On March 30, 2021, the Company entered into subordinated note purchase agreements with the Purchasers pursuant to which the Company sold and issued $15.0 million in aggregate principal amount of its 4.00% fixed-to-floating rate subordinated notes due March 31, 2031. The Company redeemed on March 31, 2026 all of the Company’s outstanding 4.00% fixed-to-floating rate 2021 Subordinated Notes due March 31, 2031, having an aggregate principal amount of $15.0 million in accordance with the terms of the 2021 Subordinated Notes. The total redemption price was 100% of the aggregate principal amount of the 2021 Subordinated Notes, plus interest accrued and unpaid to March 31, 2026.
Note 7 – Derivative Financial Instruments
ACNB is exposed to certain risks arising from both its business operations and economic conditions. ACNB manages market risk, including interest rate risk, primarily by managing the amount, sources and duration of its assets and liabilities and the use of derivative financial instruments. Specifically, the Corporation enters into derivative financial instruments to manage interest rate risk that arise from business operations.
All derivatives are recognized as either assets or liabilities in the Consolidated Statements of Condition. Until a derivative is settled, favorable changes in fair values result in unrealized gains that are recognized as assets, while unfavorable changes result in unrealized losses that are recognized as liabilities.
The Company may enter into a risk participation agreement with another institution as a means to assume a portion of the credit risk associated with a loan structure which includes a derivative instrument, in exchange for fee income commensurate with the risk assumed. This type of derivative is referred to as sold credit protection. In addition, in an effort to reduce the credit risk associated with an interest rate swap agreement with a borrower for whom the Company has provided a loan structured with a derivative, the Company may purchase an RPA from an institution participating in the facility in exchange for a fee commensurate with the risk shared. This type of derivative is referred to as purchased credit protection.

Note 8 – Fair Value Measurements
Fair value is the exchange price that would be received to sell the asset or paid to transfer the liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date.
Fair value measurement establishes a fair value hierarchy that prioritizes the inputs to valuation methods used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:
Level 1 — Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.
25

Table of Contents
Level 2 — Quoted prices for similar assets or liabilities in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability.
Level 3 — Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported with little or no market activity).
An asset or liability’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.
The following tables present assets and liabilities carried at fair value and the basis of measurement used at the periods presented:

Table of Contents
The valuation techniques used to measure fair value for the items in the preceding tables are as follows:
Equity securities — The fair value of equity securities with readily determinable fair values is recorded on the Consolidated Statements of Condition, with realized and unrealized gains and losses reported in noninterest income on the Consolidated Statements of Income. They are classified as Level 1 assets.
Available for sale investment securities — Included in this asset category are debt and pass through securities. Level 2 investment securities are valued by a third-party pricing service. The pricing service uses pricing models that vary based on asset class and incorporate available market information, including quoted prices of investment securities with similar characteristics. Because many fixed income securities do not trade on a daily basis, pricing models use available information, as applicable, through processes such as benchmark yield curves, benchmarking of like securities, sector groupings and matrix pricing. Standard market inputs include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data, including market research publications. For certain security types, additional inputs may be used, or some of the standard market inputs may not be applicable.
•     U.S. Government and agencies — Fair values are determined by a third-party pricing service, as detailed above. These debt securities are classified as Level 2.
•     Collateralized mortgage obligations, Mortgage-backed securities and State and Municipal securities — Fair values are determined by a third-party pricing service, as detailed above. These debt securities are classified as Level 2.
•     Corporate bonds — This category consists of subordinated and senior debt issued by financial institutions and the fair values for these corporate debt securities are determined by a third-party pricing service, as detailed above. They are classified as Level 2 investments.
Loans held for sale — This category includes mortgage loans HFS that are measured at fair value utilizing Level 2 measurements. Fair values are measured as the price that secondary market investors were offering for loans with similar characteristics.
Derivative financial instruments — Derivative financial instruments include interest rate lock commitments, forward commitments and interest rate derivatives. The fair value of interest rate lock commitments is derived from the value of the underlying loans, adjusted for changes in market interest rates relative to the committed rate. The fair value of forward commitments is based on quoted prices for mortgage-backed securities with similar characteristics. The fair value of interest rate derivatives and risk participations is based upon broker quotes. The fair value of both the assets and the related liabilities are determined in the same manner and are all classified as Level 2 assets.
Individually evaluated loans — This category consists of loans that were individually evaluated for impairment and have a specific reserve. They are classified as Level 3 assets.
Foreclosed assets held for resale — This category consists of foreclosed assets that are held for resale and classified as Level 3 assets, for which the fair values were based on estimated selling prices less estimated selling costs for similar assets in active markets.

1Fair value is generally determined through management’s estimate or independent third-party appraisals of the underlying collateral, which generally
includes various Level 3 inputs which are not observable.
2Appraisals may be adjusted downward by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range of liquidation expenses and other appraisal adjustments are presented as a percentage of the appraisal. Higher downward adjustments are caused by negative changes to the collateral or conditions in the real estate market, actual offers or sales contracts received and/or age of the appraisal.
Management uses its best judgment in estimating the fair value of the Corporation’s financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts the Corporation could have realized in a sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective reporting dates and have not been reevaluated or updated for purposes of these Consolidated Financial Statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each period end. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between the Corporation’s disclosures and those of other companies may not be meaningful.
FHLB and Atlantic Community Banker’s Bank stock represent restricted investments and are carried at cost less any impairment on the Consolidated Statements of Condition, which is a reasonable estimate of fair value. There was no impairment identified as of September 30, 2026 or December 31, 2025.

Net Periodic Benefit Income$(256)$(195)$(768)$(584)
The Corporation has determined that it will not be contributing to the defined benefit plan in 2026 based on current levels and expected returns on plan assets. Effective April 1, 2012, no inactive or former participant in the plan is eligible to again participate in the plan and no employee hired after March 31, 2012 is eligible to participate in the plan.
Note 10 – Commitments and Contingencies
Commitments
The Corporation is a party to financial instruments with OBS risk in the normal course of business to meet the financing needs of its customers. These financial instruments consist primarily of commitments to extend credit (typically mortgages and commercial loans) and, to a lesser extent, standby letters of credit. To varying degrees, these instruments involve elements of credit and interest rate risk in excess of the amount recognized on the Consolidated Statements of Condition.
The Corporation’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual amount of those instruments. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on balance sheet instruments. The Corporation does not anticipate any material losses from these commitments.
Commitments to extend credit, including commitments to grant loans and unfunded commitments under lines of credit, are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Corporation evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Corporation upon extensions of credit, is based on management’s credit evaluation of the customer. Collateral held varies but may include accounts receivable, inventory, property and equipment and income-producing commercial properties. On loans secured by real estate, the Corporation generally requires loan to value ratios of no greater than 80%.
Standby letters of credit are conditional commitments issued by the Corporation to guarantee the performance of a customer to a third-party. Those guarantees are primarily issued to support public and private borrowing arrangements and similar transactions. The terms of the letters of credit vary and may have renewal features. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. The Corporation generally holds collateral and/or personal guarantees supporting those commitments for which collateral is deemed necessary. Management believes that the proceeds obtained through a liquidation of such collateral and the enforcement of guarantees would be sufficient to cover the maximum potential amount of future payments required under the corresponding guarantees.
The Corporation maintains a $5.0 million unsecured line of credit with a correspondent bank. The Corporation guarantees a note related to a $1.5 million commercial line of credit with a correspondent bank, with normal terms and conditions for such a line, for ACNB Insurance Services, the borrower. The commercial line of credit is for general working capital needs as they arise by ACNB Insurance Services. The liability is recorded for the net drawn amount of this line, no further liability is recorded for the remaining line as to the guarantor’s obligation as the guarantor would have full recourse from all assets of its wholly-owned subsidiary. There were no advances on these lines at September 30, 2026 and at December 31, 2025.
The Corporation has not been required to perform on any financial guarantees and has not incurred any losses on its commitments during the past three years.

Executive Overview
ACNB Corporation is the financial holding company for the wholly-owned subsidiaries of ACNB Bank and ACNB Insurance Services. ACNB Bank provides a full range of retail and commercial financial services in Pennsylvania and Maryland primarily through its network of 33 community banking offices and two loan production offices. ACNB Insurance Services offers a broad range of property, casualty, health, life and disability insurance serving personal and commercial clients through office locations in Westminster, Maryland, and Gettysburg, Pennsylvania and is licensed to do business in 46 states.
The primary source of the Corporation’s revenues is net interest income derived from interest earned on loans and investments, less deposit and borrowing funding costs. Revenues are influenced by general economic factors, including market interest rates, the economies of the markets served, stock market conditions, as well as competitive forces within the markets. The Corporation also generates revenue through commissions and fees earned on various services and financial products offered to its customers and through gains on sales of assets such as loans, investments and properties. The Corporation incurs expenses to generate the revenue through provision for credit losses, noninterest expense and income taxes. The Corporation’s overall strategy is to increase loan growth in its local markets while maintaining a reasonable funding base by offering competitive deposit products and services.
Financial results for the nine months ended September 30, 2025 were impacted by two discrete items that were related to the Acquisition of Traditions Bancorp, Inc. which was completed on February 1, 2025: a provision for credit losses on non-PCD loans of $4.2 million, net of taxes, and merger-related expenses totaling $7.9 million, net of taxes. Financial results for the nine months ended September 30, 2025 include ACNB’s standalone results for the month of January 2025.

Summary Financial Results
•Net Interest Income — Net interest income was $34.8 million for the three months ended September 30, 2026 compared to $32.1 million for the same period of 2025, an increase of $2.6 million. For the nine months ended September 30, 2026, net interest income was $101.3 million compared to $90.2 million for the same period of 2025, an increase of $11.1 million. The increase in net interest income was driven primarily by loan growth and loans and investment securities funded at higher rates than those that paid off or matured, and the continued benefit of lower funding costs. In addition, the yield on investment securities during the nine months ended September 30, 2026 compared to the same period in the prior year was impacted by a repositioning of the investment securities portfolio completed during the three months ended December 31, 2025.
◦Net Interest Margin — FTE net interest margin increased to 4.56% for the three months ended September 30, 2026 compared to 4.27% in the same period of 2025, an increase of 29 bps. FTE net interest margin increased to 4.53% for the nine months ended September 30, 2026 compared to 4.19% in the same period of 2025, an increase of 34 bps. The accretion impact of acquisition accounting adjustments on loans and deposits from the
35


Acquisition was $1.6 million and $2.1 million for the three months ended September 30, 2026 and 2025, respectively, and $5.2 million and $5.8 million for the nine months ended September 30, 2026 and 2025, respectively.
◦Loan Growth — Average loans increased $60.6 million for the three months ended September 30, 2026, compared to the same period of 2025, driven primarily by growth in the commercial real estate portfolio and increased $104.6 million for the nine months ended September 30, 2026, compared to the same period of 2025 driven primarily by growth in the commercial real estate portfolio and the Acquisition.
◦Deposit Growth — Average noninterest-bearing deposits increased $21.6 million and $27.7 million for the three and nine months ended September 30, 2026, respectively, compared to the same periods of 2025 driven primarily by promotional incentives on commercial checking accounts and the Acquisition. Average interest-bearing deposits increased $1.4 million for three months ended September 30, 2026 compared to the same period of 2025 driven primarily by an increase in time deposits due to ongoing promotions and organic growth in interest-bearing demand deposits partially offset by attrition of higher cost money market deposits from the Acquisition. Average interest-bearing deposits increased $45.9 million for the nine months ended September 30, 2026 compared to the same period of 2025 driven primarily by the timing of the Acquisition.
◦Yield on Average Earning Assets — For the three and nine months ended September 30, 2026, the yields on average earning assets were 5.88% and 5.84%, respectively, an increase of 24 and 26 bps compared to the same periods of 2025.
◦Rate on Average Interest-bearing Liabilities — For the three and nine months ended September 30, 2026, the rates on average interest-bearing liabilities were 1.80% and 1.76%, respectively, a decrease of 3 and 8 bps, respectively, compared to the same periods of 2025.
•Asset Quality — The allowance for credit losses was $25.0 million at September 30, 2026, compared to $23.7 million at December 31, 2025. The increase was driven primarily by a specific allowance allocation on a relationship in the commercial and industrial portfolio and, to a lesser extent, loan growth; Management does not believe the increase is indicative of a general weakness in the overall loan portfolio but rather the increase is driven primarily by an isolated credit issue specific to an individual borrower.
◦Annualized net charge-offs to total average loans outstanding for both the three and nine months ended September 30, 2026 and 2025 were 0.02% and 0.01%, respectively.
◦Non-performing loans were $10.7 million, or 0.45%, of total loans at September 30, 2026 compared to $10.0 million, or 0.43%, of total loans at September 30, 2025. The increase was driven primarily by the migration of four loans to three unrelated borrowers totaling $1.4 million to nonaccrual and an increase in greater than or equal to 90 days past due and accruing partially offset by charge-offs, the movement of several loans to foreclosed assets held for resale and paydowns.
•Noninterest income — Noninterest income was $9.0 million and $26.1 million for the three and nine months ended September 30, 2026, respectively, an increase of $621 thousand and $1.8 million, respectively, for the same periods of 2025. The increase for the three months ended September 30, 2026 was driven primarily by the gain on life insurance proceeds as the result of a death benefit received, partially offset by lower gain from mortgage loans held for sale. In addition to the impact of the Acquisition, the increase for the nine months ended September 30, 2026 compared to the same period of 2025 was driven primarily by the gain on life insurance proceeds, earnings on investment in bank-owned life insurance and higher wealth management income.
•Noninterest expenses — Noninterest expense was $23.2 million and $70.0 million for the three and nine months ended September 30, 2026, respectively, an increase of $859 thousand and a decrease of $7.1 million for the same periods of 2025, respectively. The increase was driven primarily by higher salaries and employee benefits expenses and professional services expenses partially offset by merger-related expenses due to the Acquisition during the three months ended September 30, 2025. The decrease for the nine months ended September 30, 2026 was driven primarily by merger-related expenses due to the Acquisition.

CRITICAL ACCOUNTING ESTIMATES
The accounting policies that the Corporation’s management deems to be most important to the portrayal of its financial condition and results of operations because they require management’s most difficult, subjective or complex judgment often result in the need to make estimates about the effect of such matters which are inherently uncertain. The following accounting estimate is deemed to be critical by management:
Allowance for Credit Losses — The ACL represents an amount which, in management’s judgment, is adequate to absorb expected credit losses on outstanding loans at the balance sheet date based on the evaluation of the size and current risk characteristics of the loan portfolio, past events, current conditions, reasonable and supportable forecasts of future economic conditions and prepayment experience. The ACL is measured and recorded upon the initial recognition of a financial asset. The ACL is reduced by charge-offs, net of recoveries of previous losses, and is increased or decreased by a provision for (reversal of) credit losses, which is recorded as a current period operating expense.
Determination of an appropriate ACL is inherently complex and requires the use of significant and highly subjective estimates. The reasonableness of the ACL is reviewed quarterly by management.
Management believes it uses relevant information available to make determinations about the ACL and that it has established the existing allowance in accordance with GAAP. However, the determination of the ACL requires significant judgment, and estimates of expected credit losses in the loan portfolio can vary from the amounts actually observed. While management uses available information to recognize expected credit losses, future additions to the ACL may be necessary based on changes in the loans comprising the portfolio, changes in the current and forecasted economic conditions, changes in the interest rate environment which may directly impact prepayment and curtailment rate assumption, and changes in the financial condition of borrowers. As of September 30, 2026, the Company believes that its ACL was adequate.
RESULTS OF OPERATIONS
Three months ended September 30, 2026 compared to three months ended September 30, 2025
Net income for the three months ended September 30, 2026 was $15.7 million, or $1.55 diluted earnings per share, compared to net income of $14.9 million, or $1.42 diluted earnings per share for the same period of 2025, an increase of $857 thousand, or $0.13 diluted earnings per share. The financial results for the three months ended September 30, 2025 were impacted by merger-related expenses, net of taxes, totaling $131 thousand.
Net Interest Income
Net interest income totaled $34.8 million for the three months ended September 30, 2026 compared to $32.1 million for the same period of 2025, an increase of $2.6 million. The FTE net interest margin for the three months ended September 30, 2026 was 4.56%, a 29 bps increase from 4.27% for the same period of 2025. The increase in net interest income and FTE net interest margin was driven primarily by loan growth, higher yielding assets and the continued benefit of lower funding costs. In addition, the repositioning of the investment securities portfolio completed during the three months ended December 31, 2025 contributed to higher yields. The accretion impact of acquisition accounting adjustments on loans and deposits from the Acquisition was $1.6 million and $2.1 million for the three months ended September 30, 2026 and 2025, respectively. The Corporation manages the risk associated with changes in interest rates through the techniques described within Item 3, “Quantitative and Qualitative Disclosures About Market Risk” in this Quarterly Report on Form 10-Q.

3 Average balance of investment securities is computed at fair value.

Total FTE interest income increased $2.5 million during the three months ended September 30, 2026 compared to the same period of 2025, driven primarily by an increase in yield of interest-earning assets, which was driven primarily by the repositioning of the investment securities portfolio, as well as loans and investment securities funded at higher rates than those that paid off or matured. Also contributing to the increase was growth of $60.6 million in average loan balances primarily in the commercial real estate portfolio.
Total interest expense decreased $177 thousand during the three months ended September 30, 2026 compared to the same period of 2025, driven primarily by lower average balances and costs of interest-bearing deposits, mainly a result of attrition of higher cost money market and time deposits that were from the Acquisition, as well as lower average borrowings.
Provision for Credit Losses and Unfunded Commitments
The provision for credit losses was $1.1 million for the three months ended September 30, 2026 compared to a reversal of $584 thousand for the same period of 2025, and was driven primarily by a specific allowance allocation on a relationship in the commercial and industrial portfolio and, to a lesser extent, loan growth; management does not believe the increase is indicative of a general weakness in the overall loan portfolio but rather the increase is driven primarily by an isolated credit issue specific to an individual borrower. The reversal of the provision for unfunded commitments was $170 thousand for the three months ended September 30, 2026 compared to a reversal of $145 thousand for the same period of 2025 driven primarily by a reduction in exposure. The Corporation assesses risks and reserves required compared with the balances in the ACL and unfunded commitments on a quarterly basis.

Income Taxes
The Corporation recognized income tax expense of $4.0 million during both the three months ended September 30, 2026 and 2025. The provision for income taxes reflects a combined Federal and State ETR of 20.1% and 21.4% for the three months ended September 30, 2026 and 2025, respectively. The variances from the federal statutory rate of 21% are generally due to tax-free income, which includes, but not limited to, interest income on tax-free loans and investment securities, income from bank-owned life insurance policies, death benefits received on life insurance policies, federal income tax credits and the impact of non-tax deductible expenses such as certain merger-related costs and state taxes.
Nine months ended September 30, 2026 compared to nine months ended September 30, 2025
Net income for the nine months ended September 30, 2026 was $44.6 million, or $4.36 diluted earnings per share, compared to net income of $26.2 million, or $2.56 diluted earnings per share for the same period of 2025, an increase of $18.4 million and $1.80 diluted earnings per share. The increase in net income for the nine months ended September 30, 2026 was driven primarily by higher net interest income and the impact of two discrete items for the nine months ended September 30, 2025 that were related to the Acquisition: a provision for credit losses on non-PCD loans of $4.2 million, net of taxes, and merger-related expenses totaling $7.9 million, net of taxes. Financial results for the nine months ended September 30, 2025 include ACNB’s standalone results for the month of January 2025.
Net Interest Income
Net interest income totaled $101.3 million for the nine months ended September 30, 2026 compared to $90.2 million for the same period of 2025, an increase of $11.1 million. The FTE net interest margin for the nine months ended September 30, 2026 was 4.53%, a 34 bps increase from 4.19% for the same period of 2025. The increases were driven primarily by loan growth and loans and investment securities funded at higher rates than those that paid off or matured, and the continued benefit of lower funding costs. In addition, the yield on investment securities was impacted by a repositioning of the investment securities portfolio completed during the three months ended December 31, 2025. The accretion impact of acquisition accounting adjustments on loans and deposits from the Acquisition was $5.2 million and $5.8 million for the nine months ended September 30, 2026 and 2025, respectively.

Total FTE interest income increased $10.6 million during the nine months ended September 30, 2026 compared to the same period of 2025 driven primarily by loan growth and higher yielding assets. Average loan balances grew $104.6 million concentrated in the commercial real estate portfolio. The repositioning of the investment securities portfolio which was completed during the three months ended December 31, 2025 contributed to higher yields on the investment securities portfolio.
Total interest expense decreased $541 thousand during the nine months ended September 30, 2026 compared to the same period of 2025 driven primarily by lower average costs of interest-bearing deposits, as a result of attrition of higher cost money market and time deposits from the Acquisition. The average cost of interest-bearing deposits was 1.36% for the nine months ended September 30, 2026, a decrease of 7 bps compared to the same period of 2025.
Provision for Credit Losses and Unfunded Commitments
The provision for credit losses was $1.6 million for the nine months ended September 30, 2026 compared to $5.2 million for the same period of 2025. The 2025 provision expense was driven primarily by a provision for credit losses of $5.5 million for acquired non-PCD loans, and the provision for 2026 was driven primarily by a specific allowance allocation on a relationship in the commercial and industrial portfolio and, to a lesser extent, loan growth. The provision for unfunded commitments was a reversal of $290 thousand compared to a reversal of $979 thousand for the same period of 2025. The reversal of the provision for unfunded commitments for the nine months ended September 30, 2025 was impacted by the incorporation of post-COVID

Income Taxes

The Corporation recognized income taxes of $11.6 million for the nine months ended September 30, 2026 compared to $7.0 million during the same period of 2025. The provision for income taxes for the nine months ended September 30, 2026 and 2025 reflect a combined Federal and State ETR of 20.6% and 21.1%, respectively. The variances from the federal statutory rate of 21% are generally due to tax-free income, which includes, but is not limited to, interest income on tax-free loans and investment securities, income from bank-owned life insurance policies, death benefits received on life insurance policies, federal income tax credits and the impact of non-tax deductible expenses such as certain merger-related costs and state taxes.

FINANCIAL CONDITION
Investment Securities

45


Total loans, net of unearned income, increased $76.0 million, or 3.3%, from December 31, 2025 to September 30, 2026. The increase was driven primarily by growth in the commercial real estate, commercial and industrial and real estate construction portfolios. Total acquisition accounting adjustments on loans were $12.9 million and $18.2 million at September 30, 2026 and December 31, 2025, respectively. The majority of the loan acquisition accounting adjustments are expected to accrete back through as income as loans amortize and pay off. ACNB does not have a significant concentration of credit risk with any single borrower, industry, or geographic location other than within its Market Area.
The commercial real estate portfolio, which includes farmland, multifamily, owner-occupied and non-owner occupied commercial real estate, grew $50.7 million, or 4.0%, compared to December 31, 2025 driven primarily by farmland ($42.0 million), owner-occupied balances ($18.0 million) and multifamily ($12.3 million) partially offset by a decrease in non-owner occupied balances ($24.6 million). The following data related to the commercial real estate portfolio through the breakout charts excludes the impact of the acquisition accounting adjustments on loans. The collateral for these loans is primarily spread across Pennsylvania and Maryland at 66.3% and 31.5%, respectively, as of September 30, 2026, compared to 65.8% and 32.1%, respectively, as of December 31, 2025. Less than 2% of the portfolio is for real estate in urban areas of Baltimore, Maryland and Philadelphia, Pennsylvania. The largest sectors of the commercial real estate portfolio are retail and mixed-use commercial rental units, office complexes, apartment complexes and hotels, motels and bed and breakfast entities. Non-owner occupied commercial real estate represented 63.1% of the commercial real estate portfolio. Non-owner occupied commercial real estate borrowers are geographically dispersed throughout ACNB’s Market Area and are leasing commercial properties to a varied group of tenants including medical offices, retail space, and other commercial purpose facilities. Because of the varied nature of the tenants, in aggregate, management believes that these loans present an acceptable risk when compared to commercial loans in general.
The following chart details the percentage of the various categories included in the portfolio:
32403241
_____________________________________________________________
1 Constitutes over 40 loan categories that do not fit into the categories presented above, with no loan category representing more than 3% of the total.
The concentration of non-owner occupied commercial real estate, construction and multi-family was 224.7% of total risk-based capital of the Bank as of September 30, 2026 compared to 239.0% of total risk-based capital of the Bank as of December 31, 2025.
Residential real estate mortgages totaled $605.8 million, an increase of $6.8 million, or 1.1%, compared to December 31, 2025. Included in the residential real estate mortgages are $230.4 million of commercial loans and $58.5 million of consumer loans secured by residential real estate mortgages. Approximately 85% of the first liens have a loan to value, based on the current balance to the origination value of the property, of 80% or lower. Total residential real estate mortgages include $48.8 million of junior liens. Junior liens inherently have more credit risk by virtue of the fact that another financial institution may have a

senior security position in the case of foreclosure liquidation of collateral to extinguish the debt.
Commercial and industrial totaled $217.2 million, an increase of $11.7 million, or 5.7%, compared to December 31, 2025 driven primarily by three new relationships in the Lancaster and Berks regions.
Allowance for Credit Losses and Asset Quality
The ACL at September 30, 2026 was $25.0 million, or 1.04% of total loans, net of unearned income, as compared to $23.7 million, or 1.02% of loans, at December 31, 2025 and $23.7 million, or 1.01% of loans, at September 30, 2025.

Nonaccrual loans decreased $480 thousand from December 31, 2025 to September 30, 2026 driven primarily by the movement of several loans to foreclosed assets held for resale and a pay-off. All nonaccrual loans are to borrowers located within ACNB’s Market Area and were originated by ACNB’s banking subsidiary or were part of a previous acquisition.
Assets Held for Sale
Assets HFS totaled $2.3 million at September 30, 2026 and was comprised of a building in Maryland that the Corporation intends to sell.

Total deposits$2,508,963 $2,450,185 $58,778 2.4 %

ACNB relies on deposits as a primary source of funds for lending activities. The increase in deposits from December 31, 2025 to September 30, 2026 was driven primarily by the increase in noninterest-bearing demand deposits and interest-bearing demand deposits. The increase in noninterest-bearing demand deposits was driven primarily by promotional incentives on commercial checking accounts and a seasonal influx of municipal deposits. The increase in interest-bearing demand deposits was driven primarily by an influx of seasonal municipal deposits. Historically, deposit balances fluctuate reflecting different balance levels held by local companies, government units and school districts during different times of the year. Included in total deposits at September 30, 2026 were municipal deposits totaling $136.4 million, or 5.4%, of total deposits compared to $119.3 million, or 4.9%, of total deposits at December 31, 2025. Time deposits included $45.0 million of brokered time deposits compared to $59.1 million at December 31, 2025, a decrease of $14.1 million. The loan-to-deposit ratio was 95.92% at September 30, 2026 compared to 95.12% at December 31, 2025.

ACNB’s deposit pricing function employs a disciplined pricing approach based upon liquidity needs and alternative funding rates, but also strives to price deposits to be competitive with local competition, including local government investment trusts, credit unions and larger regional banks. Based on total Bank deposits outstanding, consumer and commercial constituted approximately 59% and 41%, respectively, of total Bank deposits as of September 30, 2026 compared to approximately 61% and 39%, respectively, as of December 31, 2025. The ratio of uninsured and non-collateralized Bank deposits to total Bank deposits was 18.7% at September 30, 2026. As of September 30, 2026, cash on hand, the fair value of unencumbered investment securities and collateralized borrowing capacities at the FHLB and the Discount Window at the Bank were 322.0% of uninsured and non-collateralized Bank deposits. At September 30, 2026, deposits from the 20 largest external unrelated depositors of the Bank totaled $181.4 million, or 7.2%, of total Bank deposits compared to $177.2 million, or 7.2%, of total Bank deposits at December 31, 2025.
Borrowings
Short-term borrowings are comprised of securities sold under agreements to repurchase, short-term borrowings from the FHLB and federal funds purchased. Agreements to repurchase accounts are within the commercial and local government customer base and have attributes similar to core deposits. Investment securities are pledged in sufficient amounts to collateralize these agreements. Short-term FHLB borrowings are used for general balance sheet management. As of September 30, 2026, short-term borrowings were $116.5 million, an increase of $51.8 million compared to $64.7 million at December 31, 2025. Short-term FHLB advances were $90.0 million at September 30, 2026 compared to $45.0 million at December 31, 2025, the increase from prior periods was used to fund loan growth. Compared to December 31, 2025, securities sold under repurchase agreements balances increased by $3.6 million, or 22.1%, due to normal changes in the cash flow position of ACNB’s commercial and local government customer base.
Long-term borrowings consist of longer-term advances from the FHLB, trust preferred subordinated debt and subordinated debt. Long-term borrowings totaled $214.9 million at September 30, 2026 compared to $255.4 million at December 31, 2025. During the nine months ended September 30, 2026 the Company paid off $40.0 million of long-term FHLB borrowings. On March 12, 2026, the Company sold and issued $15.0 million in aggregate principal amount 5.875% fixed-to-floating rate subordinated notes due March 15, 2036. On March 31, 2026, the Company redeemed the $15.0 million in aggregate principal amount 4.00% fixed-to-floating rate subordinated notes that were issued on March 30, 2021. Additional borrowings will be used when necessary for a variety of risk management and funding purposes. See the Liquidity discussion below for more information on the Corporation’s ability to borrow.

Capital
ACNB’s capital management strategies are developed to provide an appropriate risk-adjusted rate of return, in the opinion of management, to shareholders, while maintaining levels above its internal minimums and “well-capitalized” regulatory position in relationship to its risk exposure. Total stockholders’ equity was $420.5 million at September 30, 2026 compared to $420.0 million at December 31, 2025. The increase to stockholders’ equity was driven by net income of $44.6 million, common stock shares issued of $750 thousand and compensation expense for restricted shares and ESPP of $1.6 million partially offset by cash dividends paid to ACNB Corporation stockholders of $17.5 million, common stock repurchases of $13.5 million and a $15.5 million change in other comprehensive losses driven primarily by unrealized losses in AFS investment securities.
ACNB Corporation has a Dividend Reinvestment and Stock Purchase Plan that provides registered holders of ACNB Corporation common stock with a convenient way to purchase additional shares of common stock by permitting participants in the plan to automatically reinvest cash dividends on all or a portion of the shares owned and to make quarterly voluntary cash payments under the terms of the plan. Participation in the plan is voluntary, and there are eligibility requirements to participate in the plan. During the nine months ended September 30, 2026, 16,753 shares were issued under this plan with proceeds in the amount of $926 thousand.
Regulatory Capital
The Corporation and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Corporation’s Consolidated Financial Statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Corporation and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain OBS items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors.
Minimum regulatory capital requirements established by Basel III rules require the Corporation and the Bank to:
•Meet a minimum Tier 1 leverage capital ratio of 4.0% of average assets;
•Meet a minimum Common Equity Tier 1 capital ratio of 4.5% of risk-weighted assets;
•Meet a minimum Tier 1 capital ratio of 6.0% of risk-weighted assets;
•Meet a minimum Total capital ratio of 8.0% of risk-weighted assets;
•Maintain a “capital conservation buffer” of 2.5% above the minimum risk-based capital requirements, which must be maintained to avoid restrictions on capital distributions and certain discretionary bonus; and,
•Comply with the definition of capital to improve the ability of regulatory capital instruments to absorb losses.

Liquidity
Effective liquidity management ensures the cash flow requirements of depositors and borrowers as well as the operating cash needs of ACNB are met. ACNB’s funds are available from a variety of sources, including assets that are readily convertible such as interest-bearing deposits with banks, maturities and repayments from the securities portfolio, scheduled repayments of loans receivable, the core deposit base, the ability to raise brokered deposits and the ability to borrow from the FHLB, Discount Window and unsecured Federal Funds line providers.
At September 30, 2026, ACNB’s banking subsidiary had borrowing capacity of approximately $1.32 billion from the FHLB, of which $1.03 billion was available. At September 30, 2026, ACNB’s banking subsidiary could borrow approximately $61.7 million from the Discount Window, of which the full amount was available. The underlying collateral at the Discount Window is made up of eligible loan collateral held in a joint-custody account under the Bank’s name.
ACNB’s banking subsidiary maintains several unsecured Federal Funds lines with correspondent banks. As of September 30, 2026, Federal Funds line capacity at the banking subsidiary was $192.0 million, of which the full amount was available. ACNB maintains a $5.0 million unsecured line of credit with a correspondent bank, all of which was available for borrowing as of September 30, 2026. The Corporation also executed a guaranty for a note related to a $1.5 million commercial line of credit from a local bank, with customary terms and conditions for such a line, for ACNB Insurance Services, the borrower and a wholly-owned subsidiary of ACNB Corporation. The commercial line of credit is for general working capital needs as they arise by ACNB Insurance Services.
50


Another source of liquidity is securities sold under repurchase agreements to customers of ACNB’s banking subsidiary totaling $19.7 million and $16.1 million at September 30, 2026 and December 31, 2025, respectively. These agreements vary in balance according to the cash flow needs of customers and competing accounts at other financial organizations.
The liquidity of the parent company also represents an important aspect of liquidity management. The parent company’s cash outflows consist principally of dividends to shareholders, common stock repurchases and corporate expenses. The main source of funding for the parent company is the dividends it receives from its subsidiaries. Federal and state banking regulations place certain legal restrictions and other practicable safety and soundness restrictions on dividends paid to the parent company from the subsidiary bank.
ACNB manages liquidity by monitoring projected cash inflows and outflows on a daily basis, and believes it has sufficient funding sources to maintain sufficient liquidity under varying degrees of business conditions for liquidity and capital resource requirements for all material short- and long-term cash requirements from known contractual and other obligations.
Off-Balance Sheet Arrangements
The Corporation is party to financial instruments with OBS risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and, to a lesser extent, standby letters of credit. At September 30, 2026, the Corporation had unfunded outstanding commitments to extend credit of $527.6 million and outstanding standby letters of credit of $22.5 million. Because these commitments generally have fixed expiration dates and many will expire without being drawn upon, the total commitment level does not necessarily represent future cash requirements.
ITEM 3 – QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
The primary objective of ACNB’s ALCO, with direct oversight from the Board, is to maximize net interest income within established policy parameters. This objective is accomplished through the management of the statement of condition composition and duration, market risk exposures arising from changing economic conditions and liquidity risk.
Market risk comprises exposure to interest rate risk, foreign currency exchange rate risk, commodity price risk and other relevant market rate or price risks. Specific to the banking industry, one of the greatest risk exposures is to that of changing market interest rates. The primary objective of monitoring ACNB’s interest rate sensitivity risk is to provide management the flexibility necessary to manage the statement of condition to minimize adverse changes in net interest income as a result of changes in the direction and level of interest rates. FOMC monetary policy, economic uncertainty, and fiscal policy changes have been significant factors affecting the task of managing interest rate sensitivity positions in recent years.
ACNB’s ALCO is a management committee responsible for monitoring and managing interest rate risk within approved policy limits utilizing earnings sensitivity simulation and economic value-at-risk models. These models are highly dependent on various assumptions, which change regularly as the statement of condition composition and market interest rates change. The key assumptions and strategies employed are analyzed, reviewed and documented at least annually by the ALCO as well as provided to the Board.
Interest Rate Risk
Interest rate risk is the exposure to fluctuations in the Bank’s future earnings (earnings at risk) and value (value at risk) resulting from changes in interest rates. This exposure results from differences between the amounts of interest-earning assets and interest-bearing liabilities that reprice within a specified time period as a result of scheduled maturities, scheduled and unscheduled repayments, the propensity of borrowers and depositors to react to changes in their economic interests and contractual loan interest rate changes.
Management attempts to manage the level of repricing and maturity mismatch through its asset/liability management processes so that fluctuations in net interest income are maintained within policy limits across a range of market conditions while satisfying liquidity and capital requirements. Management recognizes that a certain amount of interest rate risk is inherent, appropriate, and necessary to ensure the Bank’s profitability. Thus, the goal of the Bank’s interest rate risk management is to minimize the fluctuations of net interest income across all interest rate scenarios.
Management endeavors to control the exposure to changes in interest rates by understanding, reviewing and making decisions based on its risk position. The Bank primarily uses its investment securities portfolio, FHLB advances, derivatives and brokered deposits to manage its interest rate risk position. Additionally, pricing, promotion, and product development activities are directed in an effort to emphasize the loan and deposit repricing characteristics that best meet current interest rate risk objectives.
51


ACNB uses simulation analysis to assess earnings at risk and net present value analysis to assess value at risk. These methods allow management to regularly monitor both the direction and magnitude of its interest rate risk exposure. These analyses require numerous assumptions including, but are not limited to, changes in statement of condition mix, prepayment rates on loans and investment securities, cash flows and repricing of all financial instruments, changes in volumes and pricing, future shapes of the yield curve, relationship of market interest rates to each other (basis risk), credit spread and deposit sensitivity. Assumptions are based on management’s best estimates, but may not accurately reflect actual results under certain changes in interest rates due to the timing, magnitude, and frequency of rate changes and changes in market conditions and management strategies, among other factors. However, the analyses are useful in quantifying risk and providing a relative gauge of the Corporation’s interest rate risk position over time.
ACNB’s ALCO operates under management policies, approved by the Board, which define guidelines and limits on the level of risk. ALCO meets regularly and reviews its interest rate risk position and monitors various liquidity ratios to ensure a satisfactory liquidity position. By utilizing the analyses, management can determine changes that may need to be made to the asset and liability mixes to mitigate the change in net interest income under various interest rate scenarios. Management continually evaluates the condition of the economy, the pattern of market interest rates, and other economic data to inform the committee. Regulatory authorities also monitor the Corporation’s interest rate risk position along with other liquidity ratios.
Net Interest Income Sensitivity
Simulation analysis evaluates the effect of upward and downward changes in market interest rates on future net interest income. The analysis involves changing the interest rates used in determining net interest income over the next twelve months. The resulting percentage change in net interest income in various rate scenarios is an indication of Corporation’s short-term interest rate risk. The analysis assumes recent pricing trends in new loan and deposit volumes will continue while balances remain constant. Additional assumptions are applied to modify pricing under the various rate scenarios.
The simulation analysis results are presented in the table below. The Bank is currently modestly asset-sensitive as interest-earning assets are expected to reprice faster than interest-bearing liabilities.

200 2.4 %(1.1)%(10.0)%
Economic Value
Net present value analysis provides information on the risk inherent in the statement of condition that might not be considered in the simulation analysis due to the short time horizon used. The net present value of the statement of condition incorporates the discounted present value of expected asset cash flows minus the discounted present value of expected liability cash flows. The analysis involves changing the interest rates used in determining the expected cash flows and in discounting the cash flows. The resulting percentage change in net present value in various rate scenarios is an indication of the longer-term repricing risk and options embedded in the statement of condition. The results at September 30, 2026 and December 31, 2025 are reflected in the table below.
Funding cost and repricing speed will continue to be a factor in the results of the model. The behavior of the business and retail clients also varies across the rate scenarios, which is reflected in the results. To improve comparability across periods, the Bank strives to follow best practices related to the assumption setting and maintains the size and mix of the period end statement of condition; thus, the results do not reflect actions management may take through the normal course of business that would impact results.
